DESCRIPTION

The t.rast.out.xyz module exports a space time raster dataset as a list of x,y,z values into an ASCII text file.

By default, this module does not export x,y coordinates for raster cells containing a NULL value. This includes cells masked by a raster MASK. However, using the flag -i also these raster cells will be included in the exported data. t.rast.out.xyz is simply a front-end for "r.out.xyz".

EXAMPLE

# export strds without NULL cells
t.rast.out.xyz strds=mystrds output=/tmp/mystrds.csv

# export strds including NULL cells and for a certain time period
t.rast.out.xyz -i strds=mystrds output=/tmp/mystrds.csv \
 where="start_time > '2010-01-01 00:00:00'"
